This gull was briefly by Stefán Ragnarssonon the 18th of janury 2018 in Bakkatjörn (Reykjavík). This is presumably a viking gull but it has some Smith features. When posted on the gull in Iceland fb page there some views that this could be an american herring gull. While it has some features suggesting Smith, it will be hard to be sure. https://www.facebook.com/photo.php?fbid ... =3&theater
